. structing the window that a dead air space may,

at will, be created between the auxiliary window 15 member and its complemental window member to establish a low heat conductor between the two or in other words to create an insulator on the face of the auxiliary window member.

It is also an object of the invention to provide a construction wherein the auxiliary window member may, at will, be rendered operative or inoperative and, when rendered operative, auto-- matically will seal the space between itself and its complemental window member, and which is so constructed and arranged that the condensation of moisture or "sweating within said space will be reduced to the minimum.

A further object of the invention is to provide such a construction that the auxiliary window member may easily and quickly be installed in frames of already existent windows of the various types currently in use, and in providing for the interchangeability of the substantially impervious auxiliary window member and one that is pervious and of the open mesh fabric type.

Other objects will become apparent as this description progresses so it is thought not necessary to here point them out in detail.

In the drawings we have illustrated an embodiment (with certain modifications of some details thereof) of our invention wherein:

Figure 1 is a face view of the construction;

Figure 2 is a broken vertical sectional view on line 22 of Figure 1;

Figure 3 is a detail sectional view on line 3-3 of Figure l of the roller supporting housing;

Figure 4 is a horizontal sectional view on line 4-4 of Figure 1 of a portion of the construction adjacent one jamb;

Figure 5 is a detail on line 5-5 of Figure 3 of a means for securing the cover of the roller housing closed;

Figure 6 is a horizontal sectional view on line i-G of Figure 1 of one form of side guide;

Home '7 is a vertical sectional view of a modifled form of bottom rail;

Figure 8 is a horizontal sectional view of a modified form of side guide; I

Figure 9 is a vertical sectional view of another form of bottom rail, showing also the fastener means; and

Figure 10 is a view at right angles to Figure 9.

We have illustrated a window, the frame of 10 which includes jambs l, a sill 2 and a head I.

Upper and lower sash l and 5, respectively, are

shown as mounted to slide in the frame and are provided with lights 6 and I, respectively, of glass or other suitable material.

The sash is so mounted that it will effectively prevent any material passage of air through the window opening, being in the construction illustrated sealed by resilient metal weather strippins 9.

The above described construction, it must be understood, is only for the purpose of illustrating the principle of the invention as the use of other window constructions of any currently used type is contemplated.

In order that the transmission of heat through the window may be minimized we have provided the following:

An auxiliary window that is constituted, preferably, by a sheet H) of flexible light transmitting :0 material of low heat conductivity, such as the currently available transparent or translucent sheet plastics, is arranged to be positioned at the optimum distance from the sash 5 and 6 for heat difi'usion, the optimum distance being readily de- 35 terminable by those skilled in the art of heat exchange. When the auxiliary window lll is in its operative position it closes the window frame or opening and seals the space between the main window and the auxiliary window, thus creating a 40 quiescent space of low heat conductivity.

This auxiliary window in is arranged to be operated to open or close the window opening as is also, of course, the main sash.

Thus the main sash and the auxiliary window may be opened" to permit free and uninterrupted access from one to the other side of the window opening. On the other hand either the main window or the auxiliary window may be "opened" or "closed independently of the other.

When it is desired to accomplish the greatest heat dispersion both of the windows are "closed so that the quiescent space of low heat conductivity will be created and substantially sealed between them.

This dead air" space will be maintained, for

- 3 all practical purposes, regardless oi the movement of the air beyond the windows, because of the fact that both the main and auxiliary windowsare efl'ectively sealed.

This auxiliary window, in the embodiment shown, is constructed and arranged as follows:

A casing I I, having stationary top, side and end walls i2, II and Il respectively, is arranged to close the upper end of the window frame from jamb to jamb thereof. A cover It is hinged at H to the casing.

Within the casinga spring actuated roller ll of the type commonly used in roller shades, but without the escapement mechanism, is mounted within the casing The auxiliary window II, which we have stated is of flexible, light transmitting materialsuch as transparent plastic, and in this form is substantially impervious to air, is mounted on the roller is and extends through throat IQ of the casing and through which it is adapted to be raised and lowered.

As it is necessary to seal the auxiliary window transversely adjacent the top and yet permit the operation of the roller l8. we have provided a resilient, compressible seal which is made up of complemental seal elements 28 and 2|, the former carried by the wall It of the casing and the latter by the adjacent portion of the cover I6, both adjacent the throat of the casing. In the particular form illustrated in the drawings. we have shown this seal as constituted by felt strips secured within flanges on the wall I! and the cover IQ of the casing II which will act as a seal and yet will not mar the window material.-

The casing is held in its closed position by suitable securing means such as snap fasteners I! which act to hold the sealing elements under pressure against the auxiliary window materlal. The side edges of the auxiliary window are guided and sealed within side tracks 22 that are secured to the jambs of thevwindow frame.

In the form shown in Figure 6 each track is preferably made of a single piece of material that is adjustabiy secured to a support 23 that is, in operation, secured to the jamb by means such as screws 24, the adjustable securement being ac-- complished by means such as screws 25 which extend through slots in the guide and into threaded openings in the support,

Each of these guides carries complemental resilient compressible sealing elements 26 between which the adjacent edge of the auxiliary window is adapted to slide in friction contact.

In the form of side track construction shown in Figure 8, the angle support 23' is preferably of a single piece of material turned upon itself to form a channel to receive the side track 22'. In this form the side track is adiustably secured to the support 23' by securing means such as screws 25' that are journaled in the support and have screw threaded engagement with the guide. In this form the guide is provided with similar sealing elements 26'.

In each form the sealing elements are preferably held in position by the crimped edges 21 of the guide which, it will be noted, are spaced apart to form a channel 28.

Thus the top and sides of the auxiliary window are sealed during all movements of the window.

In the form shown in Figure 1, the lower edge of the auxiliary window material is clamped between two separable elements 29 and ti! of a bottom rail which elements are secured together by and held in a channel at the lower side of the.

4 rial being provided with a beading 82. menses ll extend from the bottom of the rail and secure therebetween a sealing element 34 preferably of the character already described, which sealing element is adapted forcibly to contact the sill 2 to seal the bottom of the window.

In order that the auxiliary window may be guided in its up and down movements, guides 8| extend beyond the edges of the bottom rail and into the channels 28 in which they are adapted to slide.

-A modified form of bottom rail is disclosed in Figure 7 wherein one of the separable elements 28' is bent back upon itself at 30 to form a clamping means in which the bent over lower edge oi the auxiliary window material is seated, the material passing between the two elements of the bottom rail and being secured thereto by suitable means such as screws 3|. These screws also act to clamp the strip 34 to the bottom rail.

In the form of bottom rail disclosed in Figure 9 the two elements 28" and ill" are separable but held together by means similar to those described in connection with Figure '7. The folded over lower edge 01' the auxiliary window material is clamped in place against the inner wall of one of the elements of the bottom rail by projections 3|" on the other. The guide It" is located in a channel formed between the elements on the bottom rail as shown in the drawing and the lower sealing element 34" is compressed within rail.

In each form of bottom rail, a catch device 38 and a finger piece 31 are provided so that the window may be raised and lowered and secured in its lowered position against the action of the spring actuated roller it.

Thus, we have provided means for creating a quiescent zone between the inside and outside of a room without material light'interruptlon, and in so doing we have made it possible to use the two window members in cooperation, or to use only one of the members as desired. Moreover,

because of the described construction, we have.

provided for the easy and quick application and operation of the auxiliary window construction and for its replacement in the event such replacement is necessary.

When it becomes desirable to replace the impervious auxiliary window with one that is pervious (such as screening), either of two things may be done. carried by the roller l8 (with the window material pervious instead of impervious), may be substituted by the simple removal of the unit from the casing, the removal of the guides carried by the lower rail from the tracks and the replacement by the new unit or the impervious window material may be replaced by a pervious material such, for instance, as a plastic screen fabric, the other elements of the unit remaining the same.

It will be noted that the bracket ends of the casing, in which the bearings of the roller are mounted, are extended to form shade receiving brackets 38, by which a shade 39 may be carried.

The construction is such that a roller carrying an impervious element may easily be removed and replaced by one carrying a pervious element or vice versa and is such that by simple arrangement, an auxiliary window element (pervious or impervious), a shade and a curtain holder may be mounted or dismounted as a unit and replaced.
